A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

According to Winston Churchill, Alan Turing made the single biggest contribution to the Allied victory over Nazi Germany with his code-breaking machine. The world is also indebted to Turing's genius for the modern computer. It was clear that Turing had a remarkable mind from an early age. He taught himself to read in just three weeks. At his first school, the headmistress said, 'I have had clever and hardworking boys, but Alan has genius.' In 1954, he was found dead, poisoned by an apple laced with cyanide. This is the story of his life.

Explores the life of the mathematician, reveals the character of the man behind such concepts as the universal machine and the scientific understanding of the mind, and discusses his pioneering role in electronic computer design.

Forward-thinking investors are constantly looking for the next BRIC-what foreign market is on the brink of expansive growth? Will these investments payoff, or are the potential risks too great? Investing in these emerging markets requires a careful analysis of potential risks and benefits which vary greatly from country to country and even from day to day. In Cracking the Emerging Markets Enigma, emerging markets expert Andrew Karolyi outlines a practical strategy for evaluating the opportunities and-more importantly-the risks of investing in emerging markets. Karolyi's proposed system evaluates multiple dimensions of the potential risks faced by prospective investors. These categories of risk reflect the uneven quality or fragility of the various institutions designed to assure integrity in capital markets-political stability, corporate opacity, limits placed on foreign investors, and more. By distilling these analyses into a numerical scoring system, Karolyi has devised a way to assess with ease emerging markets by different dimensions of risk and across all dimensions together. This novel assessment framework already has been tested in the market to great success. Researchers, students, firms, and both seasoned and novice investors are poised to gain a clear understanding of how to evaluate potential investments in emerging markets to maximize profits.
